[OpenSIPS-Users] Paid Consultation Request

[Brett Nemeroff]

That 408 doesn't make sense to me..
If you got a 408 back, the gateway you are sending to WORKS, but IT'S
destination is failing.

say for example you send to a gateway and that gateway sends to 10 different
providers.. if this call routes to provider A, which doesn't respond, then
your gateway may respond back with a 408. Where the failure isn't your
gateway, it's your gateway's upstream..
